Among angiographically mild to intermediate lesions, a high-strain pattern identified by angiography-derived RWS was associated with an increased risk of AMI events.
Study context
- Population
- Patients with ≥1 de novo mild to intermediate coronary lesion at prior angiography, hospitalized again for repeat angiography ≥1 month later
- Participants
- 44 vs 132
- Comparison
- Lesion-related acute myocardial infarction (AMI) vs matched controls without AMI
- AMIn = 44
- Controlsn = 132reference
- Outcome
- Association between angiography-derived RWS and future AMI events
Methodological detailsmatched, retrospective cohort, 3 controls per case
